Will Pacemakers Affect Airport Scanners
No: Modern pacemakers are well shielded and not susceptible to low level electromagnetic waves. ...Read more
A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more
Can digital dental xray machine malfunction and overexpose patients to radiation? Are safety mechanisms in machine/software to limit radiation levels?
Yes: You need to be hand screened -- and remember to tell them when you arrive. It will set them off -- and that will just delay you. You will be hand-screened or searched. The microwave technology does not do a good job determining what the pacemaker is, although it is getting better. ...Read moreSee 1 more doctor answer
No: It is very unlikely that an invisible fence would interfere with a pacemaker. Normally, and this is generally true of the pacemakers that have been implanted over the past 10 years or so, not much on the outside of the body can affect their function with the exception of large magnetic fields (like that of an mri). Even then, the interference is not permanent and not significantly detrimental. ...Read moreSee 1 more doctor answer
Difficult to answer: Scanners do produce electromagnetic radiation but it is non-ionizing. Ionizing radiation like x-rays are dangerous to DNA. Regard the millimetre wave radiation radiation likely it does not cause DNA damage to your tissue. There are some studies that show DNA damage outside of the cell but not really inside of the cell per say. Basically your ok for the very short time your in the scanners. ...Read more
No: No they cannot. There are not that sensitive. ...Read more
How come vp shunts don't set off the metal detectors at airports? Will titanium plates/screws set them off? Does it depend on the size of the metal?
Not iron: Vp shunts, although visible on x-ray, are not metallic and will not set off a magnetometer at the airport. Similarly, titanium is not ferromagnetic and does not set off these metal detectors as strongly as iron does. Some titanium implants are iron alloys and react more strongly in the detectors. And yes, the size of any implant makes a big difference in how much it sets off the detector. ...Read more
No: Infrared cameras record light in the beyond red end of the visible spectrum. Fires, heat lamps and the sun put out far more infrared than such cameras and many of them emit no light at all but only record the image. It is the short wavelength end that is a problem such as uv light. ...Read more
SafeForBreastImplant: If you mean a metal-detecting wand,no.If you mean the "x-ray"machine that looks at your bags,etc on a conveyor belt,probably,if ti's thick enough.If you mean the machine you walk through that rings if you left your belt on,no.But: bear in mind that stuff can be added to silicone that makes it easier to find on x-ray and could set off an alarm if enough of a metal(say,metal powder) were added to it ...Read moreSee 1 more doctor answer
Airport alarms: There is no need to carry a card or letter when you travel. If the security monitor is made more sensitive, hardware or total joint implants can set off the alarm. In this scenario, you will be pulled aside and either scanned by hand by tsa, or some other form of exam. There is nothing you can provide the tsa agent that would prevent the additional exam. Good luck! ...Read more
No known association: Mri relies on changing nuclear atomic spin, and does not change the chemical bonds of molecules, which can alter dna and cause cancer. However, the use of a contrast agent in patients called gadolinium during the procedure may induce the onset of a debilitating malady commonly known as nsf/nfd. This can cause fibrosing throughout the body. http://www.medscape.com/viewarticle/550783. ...Read moreSee 2 more doctor answers
How does bystander lightning (not a direct strike) affect implanted pacemakers, defibrillators, vagus nerve stimulators, etc...?
Usually no effect.: The lightning strike (even as a bystander - it travels through the soil & can pop up at distances far from the original strike) can have deleterious effects on your heart (causing arrhythmia) or brain (causing unconsciousness) but these are just as likely with or without an implanted device. All electronic implants have a floating ground, which means they cannot short out because of an external ch ...Read moreSee 1 more doctor answer
Is it safe to walk through medal detectors or the new body scanners at the airport while pregnant?
Yes : Yes they are safe.Get a more detailed answer ›
It depends: Mri scans place the body in a magnetic field. A metal fragment in the eye may move and create damage to the eye. A hip or knee prosthesis is unlikley to be affected but may create imaging problems because they will distort the magnetic field and the image created. ...Read moreSee 1 more doctor answer
